Unfortunately what you have wayne1956 is not even close to pure zinc. What you have is zinc aluminum die casting alloy which has been plated or coated. Zinc or zinc aluminum alloys are dull grey in color not bright and chrome colored like a faucet or door handle. The only relatively pure zinc most scrappers would see is the old grey metal weatherstripping from windows. heres a good piece of info:
